A storage cabinet has a drawer that extends and retracts on a two-part telescopic rail profile whose sections are maintained in separation by rollers allowing for relative motion between the profiles. The roller has first and second hubs (1, 2) that are free to move along the slide axis (4) side-by-side and are joined by a common cambered mantle (3) that also forms the roller running surface (5). |
